The recent CrowdStrike global outage, dubbed the largest in IT history by the media, has sent shockwaves through the IT community, forcing CIOs to re-evaluate their current cloud strategies and how they can ensure business continuity in the as-a-service era.
As CIOs grapple with the aftermath, several critical questions and strategic considerations have come to the forefront.

One of the most significant lessons from the CrowdStrike incident is the danger of vendor lock-in, particularly when organisations rely heavily on a single provider for critical systems.
Vendor lock-in refers to the scenario where a customer becomes dependent on a single vendor for products and services, making it challenging to switch to another provider without substantial costs or inconvenience.
Over-reliance on a single vendor for critical systems can create a single point of failure, as evidenced by the widespread disruption caused by the CrowdStrike outage.
For CIOs, this raises important questions about their current vendor relationships and the extent of their reliance on single vendors for critical services. It's crucial to evaluate whether the benefits of such relationships outweigh the potential risks and to explore strategies to mitigate these risks, such as diversifying vendors or implementing more rigorous oversight and testing procedures.
By spreading the risk across multiple suppliers, organisations can reduce their exposure to catastrophic failures. However, this approach requires careful planning and management to ensure seamless integration and consistent service levels.
The CrowdStrike incident also highlighted the importance of diversified cloud strategies. While cloud computing offers numerous benefits, relying solely on a single cloud provider can expose organisations to significant risks. A multi-cloud or hybrid cloud approach can help to mitigate these risks by distributing workloads across multiple platforms.
Multi-cloud strategies involve distributing workloads across multiple cloud providers, ensuring that if one provider experiences an issue, operations can continue with other providers. This approach enhances resilience and reduces the risk of total system failure.
Hybrid cloud strategies combine private and public cloud environments, allowing organisations to retain more control over sensitive data while benefiting from the scalability of public cloud services. This approach provides flexibility and can enhance data security and compliance with regulatory requirements.
By adopting a multi-cloud or hybrid cloud strategies, CIOs can improve resilience, reduce vendor lock-in, and leverage the best capabilities of different cloud providers.
However, managing multiple cloud environments can be complex and requires careful planning and coordination.
CIOs must weigh the benefits of resilience and flexibility against the potential for increased management overhead and ensure that their IT teams are equipped to handle the complexities of multiple cloud environments.
The CrowdStrike incident underscores the need for robust risk management practices. CIOs must conduct thorough risk assessments to identify potential vulnerabilities and develop strategies to mitigate them. This includes implementing effective business continuity and disaster recovery plans to ensure that operations can continue in the event of a disruption.
One key aspect of risk management is understanding concentration risk and its implications. Organisations must conduct thorough assessments to identify single points of failure and implement measures to address them. This might include diversifying vendors, enhancing testing protocols, and establishing redundancy for critical systems.
Enhanced monitoring capabilities are also essential. Continuous monitoring of systems can provide early warning signs of potential issues, allowing IT teams to respond proactively and mitigate the impact of disruptions. Incident response plans should be regularly reviewed and updated to ensure they are effective in addressing emerging threats.
While the CrowdStrike incident affected many organisations, cloud-native applications demonstrated greater resilience. These applications, built on cloud-native architectures, are designed to be highly available and scalable. They often rely on distributed systems and microservices, which can help to mitigate the impact of single points of failure.
CIOs should consider the benefits of cloud-native applications when planning their IT strategies. By leveraging cloud-native principles, organisations can enhance the resilience and availability of their critical applications, reducing the impact of incidents and ensuring continuity of service.
However, it is important to note that while cloud-native applications can offer increased resilience, they are not immune to disruptions. Cloud-native environments still rely on underlying infrastructure, such as networking and storage, which can be affected by outages.
The CrowdStrike incident serves as a stark reminder of the importance of business continuity planning. A well-crafted plan can help organisations to respond effectively to disruptions and minimise their impact.
Key elements of a business continuity plan include:
By investing in a robust business continuity plan, CIOs can increase their organisation’s resilience and protect against a wide range of threats.
The CrowdStrike incident has exposed vulnerabilities in many organisations' IT infrastructures. To build more resilient and secure IT environments, CIOs must focus on diversifying their vendor relationships, adopting robust cloud strategies, and implementing effective risk management practices. By taking these steps, organisations can better protect themselves from future disruptions and ensure business continuity.
